Electrical conditions in 3-phase submerged arc furnaces: learning from the ElMet project
Halvorsen, Svenn Anton; Sparta, Manuel; Risinggård, Vetle Kjær; Fromreide, Mads (Journal article, 2021)ElMet is the short name for a competence project (2015-2020) on electrical conditions in 3-phase submerged arc furnaces (SAFs). In the project, NORCE has cooperated closely with The Norwegian University of Science and ... -
Metamodeling of the Electrical Conditions in Submerged Arc Furnaces
Sparta, Manuel; Varagnolo, Damiano; Stråbø, Kristian; Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Martens, Harald Aagaard (Peer reviewed; Journal article, 2021)Physics-based Finite Element Methods models can be used to investigate the electrical conditions in submerged arc furnaces (SAFs). However, their explicit solution may be very demanding in terms of time and computational ... -
An Overall Furnace Model for the Silicomanganese Process
Sparta, Manuel; Risinggård, Vetle Kjær; Einarsrud, Kristian Etienne; Halvorsen, Svenn Anton (Journal article; Peer reviewed, 2021)Controlling and optimizing smelting processes in submerged-arc furnaces are complicated by the limited amount of information available regarding the internal conditions. Computer models can help to bridge this knowledge ... -
Skin and Proximity Effects in Electrodes and Furnace Shells
Herland, Egil Vålandsmyr; Sparta, Manuel; Halvorsen, Svenn Anton (Peer reviewed; Journal article, 2019)A review of two-dimensional (2D) analytical models of skin and proximity effects in large industrial furnaces with three electrodes arranged in an equilateral triangle is given. The models cover three different cases: one ... -
Understanding Scale-Up of High-Current Electrodes
Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Sparta, Manuel; Risinggård, Vetle Kjær (Peer reviewed; Journal article, 2023)A simple and generic model for the heat distribution in electrodes for primary metal production has been investigated. The equations have been analyzed focusing on understanding the scale-up of electrodes under both direct ...
